Food commercialization, hidden hunger and malnutrition: A study of food and nutrition security, focusing on the marginalized society in Sri Lanka
(2020-09)
From 2016 to 2019, a collaborative research project between the Rajarata University of Sri Lanka and the Department of Organic Food Quality and Food Culture, University of Kassel, Germany, was carried out to investigate the food commercialization, hidden hunger, and malnutrition in marginalized societies in Sri Lanka.
Consuming a healthy diet, maintaining good health, and chronic diseases is a challenge for those struggling with poverty and food insecurity for various reasons in Sri Lanka, including limited financial ...

Assessment of genetic diversity in local breeds
(2020-06)
The present study aimed at assessing genetic diversity in selected local livestock breeds in Northern Germany, and furthermore, examining some of the indices used in describing diversity in populations. The study begun with an assessment of genetic diversity in the German Angler (RVA) and Red-and-white dual-purpose (RDN) cattle breeds. Analyses of the RVA and RDN pedigrees, consisting of 93,078 and 184,358 records, respectively, revealed a number of Red Holstein (RH) sires that were influential in these breeds. Even ...

Design of a decentralised camel milk processing plant with integration of renewable energy supply
(2020)
Der Milchsektor trägt zu ca. 4% zum Bruttoinlandsprodukt (BIP) in Kenia bei und ist der größte Teil des Agrarsektors. Kenias Kamelmilch spielt eine wichtige Rolle bei der Deckung des Ernährungs- und Wirtschaftsbedarfs in den ariden und semiariden Ländern (ASALs). Trotz dieser Bedeutung gibt es nur wenige Informationen über die Konservierungstechnologien und langlebige Milchprodukte wie Kamelmilchpulver. Außerdem zeichnen sich ASALs durch eine hohe Sonneneinstrahlung aus, die für die Konservierung von Kamelmilch genutzt ...

Sustainable diets: Studies on German consumers’ intention-behavior gap
(2020-01)
Globally our practiced food systems are causing great harm to our environment including contributions to biodiversity loss, soil degradation, water pollution, and climate change, as well as to human health. Sustainable diets are crucial for solving those global diet-related problems because they are credited with a key role in the transformation of our currently practiced food systems into more sustainable ones. Increasing the practice of sustainable diets can be a starting point for initiating the needed change. ...

Challenges to ecosystem services of sustainable agriculture in West Africa
(2020)
Food security is still sub-optimal in many parts of West Africa calling for more efficient agricultural practices in mitigating food insecurity. Some of the problems faced in West African agricultural systems are bottlenecks in ruminant livestock supply, inefficiency in commercial poultry production, and loss of arthropod diversity. These issues require proper integration of farming systems, demand the closing of nutrient cycles, need diversi cation of production, and require enhancement of ecosystem services. To ...

Entwicklung einer Robotik-Lösung zur Schneckenbekämpfung in der Landwirtschaft
(2020)
Schnecken sind bedeutende Schädlinge in der Landwirtschaft. Die Ausbringung von Schneckenkorn zur Schneckenbekämpfung als Verfahren nach dem Stand der Technik hat jedoch erhebliche Nachteile. Der Erfolg ist abhängig von der vorherrschenden Witterung und damit unsicher, zudem schadet es auch Nützlingen. Eine Robotik-Lösung zu Schneckenbekämpfung arbeitet wetterunabhängig und ist in der Lage, zwischen Schädlingen und Nützlingen zu unterscheiden.
Durch einen Feldversuch konnte gezeigt werden, dass Überfahrten eines ...

Development of Energy use Profiles, Reduction Concepts, and Implementation of Renewable Energies in the Central Ugandan Pineapple Processing Chains
(2020-02)
Pineapples, like all fruits, are highly perishable and require either immediate consumption or preservation. To make them more stable and add value, four major processing methods are being employed in Uganda, i.e. drying, munaanansi (local drink), wine, and juice making. Energy is one of the main inputs required to achieve any of the processing methods. The aim of this research was to develop energy use profiles, gain insights into energy use reduction options, and to evaluate the applicability of renewable energies ...

Governance for Decent Work in Agricultural Globalisation
(2021)
In the past decades, the agricultural world has become smaller as international food businesses have become organised around a global production network. One of the main factors for the introduction of a more decentralised and flexible food and agricultural system was the wage difference between Global North and Global South actors. In addition, Global South countries have facilitated the spread of Global Agricultural Value Chain/Global Agricultural Production Networks (GAVC/GAPNs) through promoting export processing ...

The potential of UAV-based remote sensing for the prediction of aboveground biomass and N fixation in legume-grass mixtures
(2020-07)
The world population is growing steadily and with it the demand for meat and animal protein. A major source of feed for livestock is grassland, which serves as high quality and protein rich forage. In addition to permanent grassland, temporary grassland is a valuable crop rotation element, especially in organic farming, since legumes in legume-grass mixtures can fix atmospheric nitrogen (NFix). To further increase the intensification in agriculture, reliable non-destructive measurement techniques are needed as an ...
Dissertation
Development of a new methodology in sensory science to detect the intention-behaviour gap in organic food consumption and investigate the effect of this gap on consumer’s subjective wellbeing
(2020-08)
Aktuelle Umweltherausforderungen wie die globale Erwärmung, der Klimawandel und der Verlust der biologischen Vielfalt und der natürlichen Ressourcen hängen mit dem Verhalten der Menschen zusammen. Nicht nachhaltige Produktion und Konsum erklären die meisten dieser Herausforderungen. Daher interessieren sich immer mehr Verbraucher für Bio-Lebensmittel, um ihr Engagement für ein nachhaltigeres Lebensmittelverhalten zu demonstrieren. Infolgedessen ist der Markt für Bio-Lebensmittel in letzter Zeit gewachsen. Verbraucher ...
